Understanding of Data
Data Science is a combination of various disciplines. They focus on analyzing the data and finding the best solutions. Previously it was done by Mathematicians and Statistical analysts. Then this turned to AI & ML and became extremely popular.
So, it’s all about encompassing the large available data into a human-readable format. Then using it to solve the existing problems.
Common processes involved here are:
- Collecting raw data on a server.
- Label the observations.
- Data cleansing, balancing & shuffling.
Logic & Algorithms
Programming is all about LOGIC. Unless you have good critical thinking & a strong hand on logic, you will not succeed.
What is an Algorithm? It is simply a set of instructions given to a computer to perform a specific task.
You have to understand, how the algorithm functions or processes. If you succeed, BINGO, you have developed a good hand on logic.
